The date picker wheels in iOS may look pretty, but when it comes to setting an alarm in the Clock app they can really slow things down. Scrolling to the correct hour and minute, then picking AM or PM is not the simplest or easiest way to set an alarm. PadClock changes all of this for those with jailbroken devices.
Once installed, the tweak has no options to configure. PadClock does just one thing that will save anyone who frequently uses iPhone alarms a bunch of time. Instead of date picker wheels, when entering the alarm time a numerical keypad is provided. The time is directly entered using the keypad, then the AM, PM or 24 button is selected.
As you probably already guessed, the 24 button lets the Clock app know that you've entered a time in 24-hour format. For those used to using 12-hour times, AM or PM specifies what time of the day your alarm will go off. Of course, if you prefer to go back to the date picker wheel when using the Clock app, the tweak can be disabled under Settings -> PadClock or uninstalled using Cydia.
PadClock is available on Cydia from the BigBoss repo free of charge. Check here for instructions on how to jailbreak iOS 6.x with evasi0n. You can also find out how to purchase and install Cydia tweaks with this guide.
